TO ALL WHOM IT MAY CONCERIT:

Bc it lknown'thflt I, CHRAEVSF MARTINE, GfBoston, in theconnty of Suffolk, und'State of Massachusetts, have invented st new and usefull Improvement in Lamp-Wicks; and I do herebyv declare that the following is a. full, clear, and exact description of the' construction and operaziouof thesuine, reference being had; to the :recorri-` petnying thawing', forming a pzirt of this specification, in whieh- Figure 1 is :m elevation.

Figure 2 is a plan or cross-section.

Like letters indicate like parts in both figures.

In using the'ordinary wicking for lamps having (as is lcommon -iu all the best 'lumps of the day) a ratchet to raise 'and lower the wick, a difficulty is at once encountered which hns heretofore been the cause of much complaint. The wicking must be loosely bruid-ed, to allow of capillary attraction mong its bres, and it must also possess u certain degree of solidity to transmit the 'motion from the ratchet throughout thepa'rt which is 'above' that attachment. Without the first, the substance of the wick would be destroyed too soon, end the light would lbe insulcient; without thel last, the lwick would be wedged in the tube, und' the retchethave but slight e'ect in modulating the bla-Ze. To combine 'solidity with looseness of fibre is therefore :t desiderutum, but in doing this great care must be exercised that no conductor of heatto the reservoir of fluid be use'fl. The nature of rnyinvention consists in placing a. hard, non-conducting core or thread in the substance ofthe wick, against which the ratchet muy press the loosely- Woven wicking, andvwhich by its friction may carry forward the wich in the tube of the lamp. This core should` also be combustible, so that it may not'requi're other attention than thutncccssftry to regulate .the l'lume of the lamp.

T o enable others skilled in the art to make and use my said invention, I will now describe its construction' und operation.` A

A is :in ordinary piece of round wicking, loosely'woven, as usual, Vund b is a small core of some nou-conducting substance, extending through the'whole axis of the sinne. This may fbe made of a sliver of wood or cane, or, better still, of'a bunch of cotton or linen thread stitened with glue, gum,or starch. It may be thrust through the wick after the latter is made, but it is preferable to weave or braid the wicking round it.

i It is obvious that this invention can-also be applied to llztt or tubular wicks by havingV one o r more such straight, 's'tii` pieces of wood, cane, or sti'ened thread woven in with or thrust through the substance of the Wick 4 used for lamps, substantially 'as and for the purpose described.

at the places where the ratchets press.

What-I claim as' my invention, and desire to secure by Letters Patent, is- The combination of a straight, stiiish, hard, no n-conducting core or thread with the loosely-woven wickin cuss. r. MARTINE.
